Since middle ages Ryukyu Kingdom, Amami Oshima have long had faith in such an indigenous folk religion as Noro. This religion maintained sanctuaries such as Kamiyama (a holy mountain) and Kamimichi (a clean way), miya (a central plaza), toneya (a religious hut). However, Noro faces the crisis of the extinction as a result that a religious system changed under the influence of the modernization. Therefore, we investigated the succession of Noro religion in each village and relationship with ritual spaces from interview to regional inhabitant. As results, it was clarified that the village events as “the respect for the elderly festival” and Noro religion such as “the harvest festival” were gathered, to reduce the burden on local resident and to invite gallery. Moreover, it was confirmed that miya and toneya were not only easy to maintain but also utilized. On the other hand, kamiyama was maintained but is not used. Moreover, kamimichi was just before disappearance without being used.

This study aimed to explore the spatial composition and maintenance of “Utaki”(traditional sacred space) and the management of the local festivals at Kabira, Taketomi, and Hoshidate in the Yaeyama Islands, Okinawa. A spatial survey of Utaki was conducted. Further, the officers of the organization of community centers that holds each of these local festivals were interviewed. In Kabira, Utaki have a closed spatial composition and are managed by parishioners that migrants from outside the prefecture are not allowed to participate. Prayers are conducted in Utaki by a female priest called “Tsukasa” in most of the local festivals. In Taketomi, the management of Utaki differs depending on their rating in the village. Utaki have an open space like a shrine. The organization of community centers conducts festivals in which all the islanders participate. The migrants can also participate in these festivals. In Hoshidate, the organization of community centers plays a major role in the management of Utaki. Some Utaki are used as tsunami shelters and windbreaks. The organization where migrants serve as executives holds traditional festivals along with contemporary events. The above results show that the spatial composition of Utaki and the local festivals differed among the three regions. Based on this, the study makes the following suggestions. If the traditional organizations remain like in Taketomi, it is important to manage the organization to educate migrants about Utaki and the local festivals. However, if the traditional organizations are weakened, as in the case of Hoshidate, it is important for the organization of community centers to maintain traditions by making them easily accessible for the younger generations and migrants.

本研究は、神戸市の緑地協定に基づく自主管理型開発公園について、空間的特徴と協定に基づく管理や責任に関する所有者意識の実態について文献調査とアンケート調査により明らかにした。調査の結果、自主管理型開発公園は空間的特徴から「エントランス型」「分離型」「裏型」の3つに類型され、それらは開発規模や接道条件により影響されることがわかった。「エントランス型」「分離型」として計画されると公園の自主管理意識が増加し自分たちで実施できる管理項目については自主的に管理している一方で、「裏型」として計画された自主管理型公園は維持管理が外注され自主管理意識が減少することが明らかとなった。加えて、「エントランス型」「分離型」では自主管理型開発公園を地域へ開放する意識は高いが、「裏型」になるとその意識も低下することが明らかとなった。また、自主管理自体の課題も多く所有者が開発公園を自主管理するための支援の必要性も明らかとなった。今後は開発協議の時点でのデザイン誘導や維持管理の支援の仕組みを検討することで都市空間の質的な向上に寄与し、持続的な管理が可能な自主管理型開発公園の在り方が必要であると考えられる。

In this study, we identified bottom environments suitable for habitation by Vargula hilgendorfii, or the sea-firefly, whose habitat is the sea floor in shallow water, and environmental conditions which may affect habitation. The study areas included 70 points at 17 sandy areas off the eastern coast of Osaka Bay, where environmental degradation has been a concern. The quality of water and sediment on the sea floor was assessed, and the number of sea-fireflies inhabiting the locations was evaluated using bait-traps. The results showed that no or only a few sea-fireflies survive in the following places; places where salinity and dissolved oxygen were reduced due to nearby rivers, places where the bottom sediment was deoxidized due to artificial structures hindering tidal currents, and places where there was an accumulation of fine sand due to its drifting along rapid currents. The majority of the sea-fireflies live at limited locations in the center of Osaka Bay. Statistical analysis of a generalized linear model found the following conditions necessary for sea-firefly inhabitation; dissolved oxygen (explained deviance; 27.2%), oxidation-reduction potential (18.3%), salinity (12.8%), and mud content (7.3%).
